A great choice for big dogs, this comfortable and lightweight collar stops barking
with a quick spray. The collar uses Perfect Bark™ detection to ensure that
the unit can only be activated by your own dog’s bark.

The PBC00-12724 Petsafe Big Dog Spray Bark Control Collar effectively and humanely
stops barking when it is worn. When the vibration of your dog’s bark triggers
the Sensor Probe, a burst of lemon-scented spray is emitted to deter the barking.

You should notice a reduction in your dog’s barking within the first
couple of days that he wears the PBC00-12724 Petsafe Big Dog Spray Bark Control
Collar . At this point, it is important to remember the learning process is
still not complete. Dogs will “test” this new learning experience
and will increase their attempts to bark. This usually occurs during the second
week a dog wears the PBC00-12724 Petsafe Big Dog Spray Bark Control Collar.
You must place the PBC00-12724 Petsafe Big Dog Spray Bark Control Collar on
your dog in every situation when you expect him to be quiet.
